Representation in Deductive Problem-Solving: The Matrix.
Schwartz, Steven H.; Fattaleh, Daniel L.
Seventy-two Ss attempted to solve four "who-done-it" type deductive reasoning problems which varied in mode of representation, type of logical connective employed, and affirmative versus negative statement of information. Affirmative and conjunctive problems were solved more frequently than negative and disjunctive problems (all are defined in the text of the articles); however, the mode of representation in which the problem was presented had no effect. Analysis of the mode of representation actually employed (based on Ss' written protocols) revealed a marked tendency for Ss in various conditions to change the original representation of the problem. When these changes were taken cognisance of, the matrix representation was superior to other forms on all but negatively stated problems. The somewhat poorer performance of females on this task was related to their greater reluctance at changing the representation of the problems. The original hypothesis of the instrumental role of representation of information in problem-solving was supported. Suggestions are offered for subsequent investigation. (Author/KS)
